This section describes the mode switches, data entry keys, and operating keys provided
on your calculator. The following terms are used in discussing your calculator's
operation:
The accumulator is the area of the calculator's logic that stores a running total of
•
the results of addition and subtraction operations. It is the "adding machine" portion
of the calculator.
The calculating register is the area of the calculator's logic where the intermediate
•
and final results of multiplication, division and percentage calculations are stored.
The contents of the calculating register do not affect the accumulator.
The keyboard register is the area of the calculators logic that stores the value that
•
will immediately be used in the next calculation.
The item count register is the area of the calculator's logic that counts your
•
entries into the accumulator. Each positive entry is counted as one item. Each
Negative entry is subtracted resulting in a net item count. It is also net or gross
programmable.
The memory register is the area of the calculator's logic that accumulates
•
amounts you add to or subtract from the memory. Because the memory register is
independent of the accumulator and the calculating register, it retains its value until
you clear it with the Memory Total (M) key.
